Loading the involved version on the above models, in case the default route exists for both the private network (VPN-instance) and the public network while the default route in the private network (VPN-instance) fails or is deleted, the business message forwarded by the default route in the public network would be discarded incorrectly and business access fails.
The involved versions have a flaw in processing default routes. Deleting default routes within a private network (VPN-instance) does not properly carry the VPN-instance identity, resulting in the underlay table entries for public network default routes being misplaced as black hole routes.
